| Abstract: | In this paper,a novel sequential fusion estimation algorithm for the system with multiple one step delay out-of-sequence measurements is proposed.Aiming at the problem of fusion filtering with out-of-sequence measurements,the idea of sequential recursion is taken into consideration on the basis of the optimal algorithm for the system with single out-of-sequence measurement.Then,in the sense of linear minimum mean square error（LMMSE）,this paper presents an optimal sequential fusion algorithm for the system with multiple one step delay out-of-sequence measurements through directly updating.The novel method improves the real-time characteristic of the multi-OOSMs fusion estimation.The final simulation illustrates the effectiveness and optimality of the proposed method. |
